Title: Power-factor improving rectifier circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M7/217
Filed: 1993-12-13
Abstract: PURPOSE:To reduce control currents by using a time-constant inductance as the controlled winding of an orthogonal ferrite transformer, varying the control currents of a control winding in response to the rise of AC input voltage, increasing switching frequency and improving a power factor in response to AC input voltage over a wide range. CONSTITUTION:A converter drive transformer CDT and an orthogonal ferrite transformer PRT are mounted on a voltage resonance converter 7, and a time- constant inductance LB is constituted as one of the controlled windings of the orthogonal ferrite transformer PRT. The switching frequency of a switching transistor Q1 determined by a series resonance circuit consisting of the time- constant inductance LB and a time-constant capacitor CB is increased with the rise of AC input voltage VAC. Accordingly, a power factor is maintained at a fixed value or more regardless of the rise of AC input voltage while control currents IC are lowered and power loss is reduced, and the orthogonal ferrite transformer PRT can be miniaturized.

Title: Gear shift control device for vehicle
Inventor: OSHITA JUNICHI
IPC: F16H61/06
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To slowly increase a clutch connection pressure to reduce a connection shock by connecting or disconnecting an accumulator by an interrupting means to change a pressure increase pattern of a clutch when power is interrupted at the time of gear shift by utilizing a hydraulic multiple disk clutch of an advance and back change-over device. SOLUTION: When an acceleration switch 29 and a deceleration switch 30 are operated, conducting electricity to proportional pressure control valves 75, 76 of an advance and back change-over device 3 is stopped, and electricity is conducted into a change-over control valve 7 of a branch circuit 78 to disconnect an accumulator 8. After that, either of hydraulic cylinders 47A and 47B is driven in accordance with switch operation to perform gear shift. When a predetermined gear shift position is detected, conducting electricity to the proportional pressure control valves 75, 76 is restarted, and conducting electricity to the change-over control valve 7 is stopped. Consequently, a clutch pressure is slowly increased at the initial time of conducting electricity and then is increased rapidly after that (after pressure oil is filled in the accumulator 8) to reduce a gear shift shock at the time of advance and start.

Inventor: MUKAINE KIYOSHI
IPC: G11C11/419
Filed: 1995-12-27
Abstract: PROBLEM TO BE SOLVED: To improve the operating speed by providing a MOS transistor(TR) whose drain or source connects to an output node of the amplifier circuit and whose gate receives one of differential input voltages. SOLUTION: Two MOS TRs are inserted in series between both nodes VCC and VSS in a 1st stage amplifier circuit 10 and a 2nd stage amplifier circuit 20a in addition to a constant current source TR, and the constant current characteristic is identical for both the amplifier circuits. Thus, an output operating point of the 1st stage amplifier circuit 10 and an output operating point of the 2nd stage amplifier circuit 20a are matched. Since one voltage input Vin1 of the differential input voltages is applied to a gate of the NMOS TR N4, the 2nd stage amplifier circuit 20a starts amplification operation before the output of the 1st stage circuit 10 is confirmed to improve the operating speed of the differential input sense amplifier circuit.

IPC: E02F7/00
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To improve workability by flowing an excavating mixture generated at pile driving time by inside digging on the water in the other existing pile, and precipitately separating the excavating mixture into excavating earth and liquid. SOLUTION: Polluted water generated at driving time of a steel pipe pile 7 by an inside digging construction method on the water is drained to an outside upper part of the pile 7 to be injected into the driving-completed steel pipe pile 4 by piping 3a. Next, the solid content such as excavating earth in the polluted water increases by being precipitated/accumulated, and overflows in a circulating tank 1 installed by surrounding the pile 4 from the pile 4 while including the excavating earth in most of the injected polluted water, so that the excavating earth precipitates even in the tank 1. Next, treated water by precipitately separating the excavating earth is supplied to the driving pile 7 by piping 3b to be reused.  When a little suspended matter leaks outside the tank 1, diffusion is prevented by a diffusion preventive frame 2, and when oil flows out, the diffusion is prevented by an oil fence 5. Thus, execution work can be simplified without exerting influence on a peripheral environment, and a construction period and a cost can also be reduced.

Title: Cordless ringer system
Inventor: SHIMIZU SATOSHI
IPC: H04B1/00
Filed: 1992-12-24
Abstract: PURPOSE:To ring a ringer only once against a same call signal by devising the system such that a cordless ringer receiving a call signal of the same call number from a connector does not generate a call tone. CONSTITUTION:A private branch of exchange PBX sends sequentially a call signal having a separate call number to each call to each connector BS. Each connector BS receiving the signal transfers the call signal to a cordless ringer CR and in this case, the cordless ringer CR at first detects the call number to discriminate whether or not the call number is the same as the preceding call number, and generates a call tone when the call number is not the same as the preceding call number but does not generate a call tone by regarding it that the call tone is already sent when the call number is the same as the preceding call number. Thus, the ringer is not rung for twice or over against the same call signal sent from plural connectors BS in this way.

Abstract: PURPOSE:To obtain an inexpensive air bag system with high connection reliability by connecting an air bag inflator mounted on a steering wheel to a secondary coil and by constituting so that an initiating signal generated by a collision sensor is applied to a primary coil. CONSTITUTION:At collision of a vehicle, when a collision signal for detecting a collision is put into a control part 4 from a collision sensor 6, the control part 4 applies AC voltage as an initiating signal to a primary coil 2 through a DC/AC converter 5 based on this collision signal.

Filed: 1992-12-24
Abstract: PURPOSE:To search a correspondent point with high resolution by determining a correspondent point from the matrix of an optimum determined affine function and a translation vector. CONSTITUTION:The images along the epipolar line in two sheets of images R, L from right and left cameras are made as Ri, Lj respectively. If a correspondnt point exists within the two sheets of images of i=1 to N, j=1 to M, a deviation is regarded as a smooth change from a local viewpoint when the deviation occurs in the vicinity each of the correspondnt point by the three- dimensional structure of an object. A 1st-order conversion is performed for a point Ri within the image on the right side and Ri'=AiRi+Bi is made (The Ai shows a rotation, magnification/reduction, and the Bi is a vector showing a parallel move). In the same way, for the vicinity of the Ru Rj'=AiRj+Bi is performed by the Ai, Bi. In order to determine the optimum values of the Ai, Bi used here, an energy function is defined. By minimizing an energy function Ei by using each variable for the Ai, Bi, the optimum Ai, Bi are determined, and the search of the correspondent point is determined in the form of the optimum values of the Ai, Bi.
